Damien had a plan.  The family home was being occupied by Melody Tinker but he wanted the house for his mistress, Serena.  He moved in, booted Melody out, and Serena moved in.  Damien then rang up to adopt Lithia and she arrived the next day.

In the meantime Damien tried again for a boy with Serena.  Once she got pregnant he moved out again and back to Marla and the girls.  Serena and Lithia had the house to themselves.

Unfortunately for Damien, Serena had another girl (I’ve forgotten her name).
